摘要：

We prepared weakly agglomerated powders of ZrO2-CeO2 and HfO2-CeO2 solid solutions 5-8 nm in particle size, consisting of monoclinic and tetragonal phases. After heat treatment at 12000 degrees C, the crystallite size was 30 and 14 nm, respectively. We also examined the effect of precipitate freeze drying on the crystallization of hafnia-based solid solutions containing up to 20 mol % CeO2.
